Shortcircuit............If it is accessible from the attic, I try to pull it up and run the K&T into a non-metallic j box. Hopefully you have some "Loom" left to run each wire into the knockouts. The loom is the flex tube over the wire, I have been told. One wire per ko. Then tie in some good stuff to it. As long as you are 8' away from grounded appliances, I believe you will be ok. IMHO
